TestoFuel works by stimulating testosterone production and protein synthesis in the body. It also regulates insulin and glucose, which are crucial to weight control. The supplement contains D-aspartic acid, which has been shown to significantly increase testosterone levels within 12 days of use. [3] It also contains panax ginseng, which improves libido and regulates dopamine, and fenugreek, [4] which boosts metabolism, physical strength, and energy levels as well as it's effects on increasing free testosterone levels.
TestoFuel also helps reduce body fat, including stubborn belly fat. It regulates glucose and insulin levels, which speeds up and sustains fat loss. It also enhances mood and self-confidence, without depending on stimulants like caffeine. Instead, it uses natural ingredients like maca and vitamin D3 to boost confidence and improve mood.
Vitamin D: This nutrient is produced in the body when it's exposed to sunlight and is essential for a variety of bodily functions, including bone health, immune function, and hormone production. Research has shown that vitamin D can boost testosterone levels in men with low levels of this hormone. [1]
D-Aspartic Acid: This amino acid is involved in the production of testosterone and other hormones in the body. Studies have shown that supplementing with D-aspartic acid can increase testosterone levels, improve sperm quality, and enhance muscle growth. [2]
Fenugreek: This herb has been used for centuries in traditional medicine to enhance libido and male fertility. Research has shown that fenugreek can increase testosterone levels, improve sexual function, and reduce body fat. It's also been shown to boost athletic performance and improve muscle building speed.[4.5]
Zinc: This mineral is essential for many bodily functions, including immune function, wound healing, and hormone production. Research has shown that supplementing with zinc can increase testosterone levels, improve sperm quality, and enhance muscle growth. Particularly in men with even a small zinc deficiency, supplementing with the essential mineral was shown to raise both free testosterone and serum testosterone levels. [6]
Magnesium: This mineral is involved in over 300 enzymatic reactions in the body, including muscle and nerve function, blood glucose control, and hormone production. Research has shown that supplementing with magnesium can increase testosterone levels, improve muscle strength, and enhance exercise performance. [7]
Vitamin K2: This nutrient is essential for bone health and has been shown to improve testosterone levels in men with low levels of this hormone. [8]
Maca: Whilst Maca doesn't effect testosterone production directly, it has been shown to be effective for symptomatic relief of low testosterone. Mostly as a libido booster (where it has the most studies to back it's use), it has also been shown to improve energy levels, mood and athletic performance, making it a common ingredient in higher quality testosterone boosters all the same. It has also been shown to boost sperm count. [9,10]
Oyster extract: Oyster extract has a couple of benefits, it's rich in zinc, it's been shown to be an effective libido booster, although it has limited effect on testosterone levels outside of the zinc, it's a novel and decent inclusion and contributes to testofuel testosterone boosters high score in the libido category. [11]
Panax ginseng: Panax (not to be confused with American Ginseng) has been shown to stimulate natural testosterone production in both men and women with test groups who supplemented the herb showing elevated saliva testosterone levels. The dosage in TestoFuel is of course the same as the dose that was used in these trials to achieve a testosterone boost. As such it's included in a lot of quality natural testosterone boosters. As an added benefit Panax Ginseng has also been shown to imrpove mood. [12,13]
vitamin B6: Vitamin b6 is essential for testosterone production, as the body doesn't store any a lot of testosterone boosters include the ingredient and it doesn't take up much capsule space so it's generally good to see included. [14]
